Well, obviously I'm a bit biased in my decision, but I LOVE my Holley SysteMax II kit. If you look up Holley's dyno numbers for their kit with the supporting hardware, they're making 350 HP. I don't know if that's to the flywheel (probably, you'd have to call and ask them), or to the wheels, as they did mention a stall converter for the test car they used, but this kit is absolutely sick.
The cam lope is enough to turn heads from across the parking lot, and when it sits at about 800 RPMs it just sounds like it's gonna rip your head off. Just put it this way - it does NOT like getting started up on a cold day. Today I cranked it over and within 5 seconds the car stalled cause it was turning at about 500 RPMS. But when you warm the car up or drive it on a hot day, when you take your foot off the pedal and put it in neutral, you can hear the god damn cam loping in the floor it's so hard. Not to mention that it makes GREAT power, especially above 4000 RPMS.
I was in second gear going down a hill at 4500 RPMS and I took my foot off the pedal, slammed it to the floor, and the back wheels hopped off the ground. In first gear I'll go almost completely sideways if I'm not careful. It's enough power to push you into your seat.
Not to mention I've been told by several people the Holley upper and lower intake manifold is one of the best available if you're thinking about a boost application later on.
For a H/C/I kit, I'd definitely rate this as worth the money. Granted, I didn't buy this one, but if forced with another purchase later on, there is no doubt that I'd go with this kit again. Extremely pleased with it.
Also, be careful with the Trickflow Kit. I've read about SEVERAL pissed off people cause they slap that kit on and they end up making 287 RWHP when they're done. Others report gains of over 300+ RWHP. It sounds like it's hit or miss with the Trickflow kit?
I haven't seen anyone mad about the Holley though. That could also be because more people buy Trickflow kits, but still.
Good luck on your decision either way, my friend. Keep us posted.
